chore: Upgrade GitHub Actions to latest versions

[salmanmkc]

Summary

Upgrade GitHub Actions to their latest versions for improved features, bug fixes, and security updates.

Changes

Action	Old Version(s)	New Version	Release	Files
aws-actions/stale-issue-cleanup	v6	v7	Release	close-stale-issues.yml

Why upgrade?

Keeping GitHub Actions up to date ensures:

• Security: Latest security patches and fixes
• Features: Access to new functionality and improvements
• Compatibility: Better support for current GitHub features
• Performance: Optimizations and efficiency improvements

Security Note

Actions that were previously pinned to commit SHAs remain pinned to SHAs (updated to the latest release SHA) to maintain the security benefits of immutable references.

Testing

These changes only affect CI/CD workflow configurations and should not impact application functionality. The workflows should be tested by running them on a branch before merging.
